What if we told three primary grade children (under 8) the details of respiration in mitochondria (or photosynthesis, or meiosis and mitosis). We illustrate the story with chalk on the driveway. We make a list of keywords. We then ask the children questions, covering the major points of the content. They can point to the drawing. They can point to those hard keywords. Between the three kids, they will likely get some of it correct. At each critical point in the answer, a narrator of some kind comes in and gives the real answer, clearly in a blurb. If the child was close, but wrong, the narrator starts with "Nice try Grace, but ...." Would little kids 'almost getting' the concepts make the high school students feel dumb or inspired?
